Keto folks can be obnoxious, but doing a clean keto, not all bacon and cheese, is a remarkable tool to enable IF success. IF on its own it amazing if you can make it work with your schedule, but the appetite suppression of getting into ketosis is truly remarkable and makes doing IF pretty easy. I've experimented with some success too using exogenous ketones as appetite suppressants for IF.
Really it's all just understanding caloric deficit versus thinking "fat makes you fat" and finding something that works for you. Regarding fat shaming, I'm not for personally making anybody feel like they're a worthless piece of shit for being obese, but at the same time we've damn near normalized being so fat you need a scooter to grocery shop. I'm pro body positivity that keeps girls from thinking they need to be bulimic to fit an image, but there's a balance somewhere short of where we are finding ourselves now where legitimately obese chicks want to wear dental floss bikinis and be praised for their bravery. Also, fuck Big Corn.
